Original story

Google kicks off its I/O developers conference on Wednesday, where it's expected they will announce several big projects on both the hardware and software fronts.

USA TODAY will have live coverage of the I/O keynote, which starts at noon ET. So, what will Google unveil? Here's a look at what we could see revealed:

Google Glass. Google's wearable computing technology has generated plenty of buzz. The big question is what will we learn -- if anything -- from today's keynote. Do they share details on potential new partnerships and apps? How soon before consumers get their hands on Glass? For more on how Glass works, USA TODAY's Ed Baig has the details.

Will Google take on Spotify?According to The Verge, Google is going to announce a music subscription service now that it's locked out three of the four major publishing labels: Universal, Sony Music and Warner. The deals would apply to both video service YouTube and Android store Google Play. What's not clear is how much Google would charge for a music subscription.

Google Maps overhaul. The Android-focused site Droid Life says they spotted a Web page that has since been removed detailing big changes to Google's mapping application. Key features reportedly included Flight Search and increased integration with Google Earth.
